WampServer

Hi,

I have looked all over, but cannot find any clues...

I am running a fairly large (100 Dev / Test Joomla sites and many DBMS) on W'Server using 2.2a
But it seems the only way to get php 5.3.10 installed (as per Live Hosting service) is to upgrade to 2.2d

Could someone please advise...
Should I simply run uninstall_services.bat and install 2.2d to a new folder?

Then is it possible to simply copy the mysql/data folder from 2.2a install to 2.2d install ?
- or must I use phpMyAdmin to import them all to 2.2d?

Any advice would be greatly appreciated.

Thanks,
